A Summary of the WWDC25 Group Lab

I am passing a group of apps that the user did not select to the ManagedSettingsStore. I write it like this I then block the user from using this group of apps. ManagedSettingsStore().shield.applicationCategories = ShieldSettings.ActivityCategoryPolicy.all(except:familyActivitySelection.applicationTokens) This problem occurs when you select three or more categories in the FamilyActivityPicker. For example, if you select only the Education category, only the apps in the Education category will be available, but if you add the Productivity/Lifestyle category to the selected categories, all apps in the iPhone will be available. This problem occurs whether the number of categories to select is four or five. Perhaps IOS is not generating the exact set of apps when it generates the set.

Is there any way to read/write preferences for a Mac app group using the defaults command? I'm talking about the stuff you would programmatically manipulate using [NSUserDefaults initWithSuiteName:], and that is stored on disk in ~/Library/Group Containers. If I just say defaults read <suite name>, it tells me the the domain does not exist.

In Itunes Connect you can move subscription items up/down inside a subscription group to establish their relative level.But if I have essentially the same subscription, but differing only in duration, how can I assign the subscription items to the same subscription level?A user changing the subscription duration should be considered a crossgrade, not a upgrade or downgrade.I see no way to set 2 subscriptions items to the same subscription level in a subscription group in itunes Connect.Is my assumption that 2 subscription items can both have the same subscription level valid ??

I'm using a UICollectionViewCompositionalLayout, and an exception is thrown when I load my collection view.The exception says Cannot solve for a non-group item.Any idea what might be wrong? Or how to fix it?Here's my layout codefunc sideBarSectionCollectionLayout()->UICollectionViewCompositionalLayout { let size = NSCollectionLayoutSize(widthDimension:.fractionalWidth(1), heightDimension:.estimated(105)) let item = NSCollectionLayoutItem(layoutSize: size) let group = NSCollectionLayoutGroup.horizontal(layoutSize: size, subitems: [item]) let section = NSCollectionLayoutSection(group: group) section.contentInsets = NSDirectionalEdgeInsets(top: 5, leading: 5, bottom: 5, trailing: 5) section.interGroupSpacing = 5 return UICollectionViewCompositionalLayout(section: section) }My cells are set up in the storyboard.I'm running xcode 11.1 (11A1027), and catalina 10.15.1 Beta (19B68f)It started after the catalina upgrade from the GM.Here's the relevant part of the stack trace.2019

I would like to request the ability to group windows in mission control so that I can easily swap all windows between my 2 external monitors easily. Anyway to make swapping all windows between the displays easier would be a huge time saver. Making this an option in shortcuts would work as well.

I have two versions of my game, one under 100mb and one way bigger. Most users will try the game with the small version and then be promted to download the big verison to be able to play more. The light and big version of the game are in the same app group. Is it possible to share the IAP (in app purchases) for both versions? In Itunes connect its easy to import the achivments and leaderboards between the two app versions in the group. But I see no such option for the IAP...

I have been playing around with the page layout on my IPad Pro and discovered that is is impossible to group apps if you leave an empty space in the page. I found the option fun to finally place my apps where i want and not just lined up from top to bottom. I discovered if you leave gaps in the page layout it is impossible to groupe apps. The moment you hover the app over the groupe, the groupe shifts back to fill the empty space. Once I filled up all the empty space then the groupe stops moving. It is pretty annoying. The was excited to see the new feature to finally hate it completely. I do hope someone will fix this problem.

1) Main app and extension register for app groups.2) Main app gets a url from NSOpenPanel, makes a security scoped bookmark and saves is in NSUserdefaults with group container as the suite name.3) Run the extension, grab the bookmark data from user defaults and resolve it. The data is not nil, but fails to resolve:Error Domain=NSCocoaErrorDomain Code=259 The file couldn’t be opened because it isn’t in the correct format.

I seem to have found a BUG in XCode 9, however I can't submit it, so I'll submit it here and hope one of you that can submit bugs can forward it to Apple.It's an easy bug to test: Create a project, then create a Group. In Xcode 8.3.3 this would create a Group in Xcode but not a subdirectory in Finder. NOW it also generates a Subdirectory (check your finder directory). I discovered this by following some directions in a book on Core Data. I started in Xcode and created the groups as described in the book. Later I downloaded Xcode 9 and started over (creating a new project), creating the group now creates a subdirectory also. This might actually be NICE....if it weren't for the fact that some files, like info.plist are expected to be in the main project directory, or at least it errored when I moved the info.list to the Group, as described in the book (it works in Xcode 8.3.3, does not work in Xcode 9 beta 5).I tried this in iOS, as well as in macOS (both create subd

in my app i added keychain access group in capabilities, then i checked the entitlement file, the value of keychain-access-groups is 94KV3E626X.com.frank.keychainAccessGroup I turned on Automatically manage signing in xcode everything looks fine. i tested in simulator and device in debug environment, and it works fine. I could shared data across main app and app extension... but after I build the app thru pipeline and use adhoc environment and get the .app file, i run this command in terminal: codesign --display --entitlements :- myapp.app it shows the value of keychain-access-groups is NOT 94KV3E626X.com.frank.keychainAccessGroup that is defined before. it is replaced by the app id 94KV3E626X.com.frank.development.adhoc. Does anyone know why the value of keychain-access-groups is replaced? it supposes to be the one i defined in Xcode, which is 94KV3E626X.com.frank.keychainAccessGroup

With the new subscription groups, users can upgrade and downgrade from outside the app. Is there any mechanism that lets the app know when those events have happened? Or do we have to keep track of it ourselves by parsing the receipt file every time the app is opened?

I am currently having a nightmare with Xcode trying to set up App Groups I previously had it set up but since I upgraded to Xcode 7.3 it has now broken. I get the error message You don't have sufficient permissions I haven't enrolled in the developer program but I know app groups you don't need to use them. This is what is shown inside Xcode inside the permissions.Image of problem
